Asked why Guns N' Roses couldn't be signed up as 2017 Download headliners, Copping tells the That's Not Metal podcast: "It's very, very simple. We'd been talking to Guns N' Roses when it was first being mooted that Duff, Slash and Axl were talking about getting back together.

"They did Coachella and then we talked about Download. I've got to be honest, and this is gonna surprise a lot of people, but it wasn't about the money.

"To them, it was about, 'We want to go out and do our own shows.' On that touring cycle in the early 90s they came to the UK three times and played at Wembley Stadium. That is huge. They wanted to play Wembley, but it was booked. So I said they should look at the Olympic Park."

Once the band decided to play their own stadium show rather than headline at Donington, they settled on the new Olympic Stadium after Axl Rose's triumphant guest slot with AC/DC at the same venue.

Copping adds: "The thing that swung it for Guns N' Roses playing at the Olympic Stadium was that AC/DC concert.

"They just wanted to go for it. They felt it was a bigger stadium, coming back for the first time as that band, that it was a bigger statement. It was nothing to do with money."
